Abstract (en)
[origin: US4780509A] Impact-resistant thermoplastic molding materials based on a resin A containing one or more vinylaromatic monomers are prepared by reacting the resin A (component A) with one or more monomers from the group consisting of the alpha , beta -unsaturated dicarbonyl compounds (component B) by a process in which the reaction is carried out in a melt of A in the presence of B and in the absence of initiators, and the resin A used is one which contains from 3 to 50% by weight, based on A, of one or more elastomers a1 (rubber) and has been prepared in a conventional manner by polymerizing one or more vinylaromatic monomers of 8 to 12 carbon atoms in the presence of the elastomer a1 are used for the production of moldings.
